Hybrid tea rose plant named ‘Hilmoc’

ABSTRACT

Described is a hybrid tea rose plant variety producing red flowers of good form.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid tea rose variety which was originated by my crossing as seed parent the variety known as ‘Cindy’ (patented MEltinor, U.S. Plant Pat. No. 3,910) and as pollen parent the variety known as ‘Samantha’ (patented JACmantha, U.S. Plant Pat. No. 3,727). The varietal denomination of this new rose is ‘Hilmoc’.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by the new variety which distinguish it from all other red rose varieties of which I am aware are its long vase life and long stems. Asexual reproduction by budding/grafting of the new variety as performed in Richmond, Ind., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagation. Other known forms of asexual reproduction may be also used.

COMPARISON WITH PARENTS

This variety is different and distinguishes from its pollen parent ‘Samantha’ and seed-parent ‘Cindy’ by having greater vase life and stem length than ‘Samantha’ while retaining its vivid red color and possessing the high production of its seed parent ‘Cindy’.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
